At a Florida orange juice producer, they have been studying the time it takes to prepare an independent-hauler truck for shipment. This process begins when the production department notifies the traffic depart-ment to arrange for an independent hauler for a juice shipment. When the truck arrives at the plant, the truck’s information is entered into the company’s com-puterized tracking system. This paperwork includes information on previous loads and tank wash records. Since contaminants must not be allowed in juice con-sumed by humans, having a clean tank is of paramount importance. It takes 45 minutes to clean a tanker; 30 minutes round-trip travel time to the wash area and 15 minutes of actual wash. There may also be a line of trucks waiting to be washed. Once back at the plant with a clean truck, the paperwork for the truck is com-pleted, requiring an additional 5 minutes. After that, the truck is directed to the bulk storage area. Here the target time is 75 minutes +/-5 minutes, to fill the tank. Use the following information to create an X and R chart. Interpret the chart (n = 5).
